The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
It's a bit of a slow start with small, inconsistent surf, but we've got a solid run of quality swell building nicely from the 9th of August onwards. The water is sitting at a pleasant 72°, right about where it should be for this time of year, so no surprises there.
The best of the early action is Monday morning, the 3rd of August. Jaconé is firing up with a clean 4 ft swell from the ENE and glassy conditions. The wind is dead calm, so it's going to be pure, clean glass. The combined energy is moderate at 213, so it's not a beast, but it's a fun, easy-going morning.
The real standout, the one you circle on the calendar, is Sunday, the 9th of August. The morning sees a solid 7 ft SSW groundswell, with a period of 9 seconds, pushing into the exposed coastline. The wind is a light offshore from the NNE, keeping it clean. The energy reading is a strong 808. By the afternoon, it's packing a punch: 8 ft from the SSW, with a period of 11 seconds, and the combined energy jumps to 1473. That's a lot of power. The wind stays offshore from the NE. This is a session for experienced surfers – the size is proper, but the conditions are excellent. Crowds are possible here, but with this quality, it's worth the company.
Now, the week after that is a mixed bag. Monday the 10th gets blown out by strong onshore winds, so forget that. But Tuesday the 11th of August sees a big, powerful 8 ft S swell with a 14-second period, and the energy is a massive 2748. The wind is cross-off, making it rideable, but the period is long, so this will be best suited to a point or reef to handle the long lines. Wednesday morning the 12th of August is also a cracker for experienced surfers: an 8 ft SSW swell, 13 seconds, and a clean offshore breeze. The energy is huge at 2339. Thursday the 13th of August drops back but remains clean with a 5 ft S swell and a light offshore.
The second week is a lot more hit-and-miss. The weekend of the 15th of August is a write-off, with onshore winds and weak swell. However, Sunday the 16th of August looks promising. The morning has a 7 ft S swell, glassy conditions, and a huge energy reading of 1272. It's a big, powerful swell, so only for the confident crew. The afternoon gets a bit messy with a cross-on wind, but the morning window is a solid late-season option.
So, to sum it up: the first week is a slow burn, but the 9th of August is the standout. The second week offers a few powerful, experienced-surfer-only windows, but a lot of average days in between. Keep your eyes on the forecasts closer to the day.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
